Installation
MOUNTING
Mount the unit in a DRY location. Allow at least 4 inches of clearance around it for adequate
cooling.
INPUT CONNECTION
The unit is equipped with 3 foot long (1m) power leads as a DC input connection. This should
normally be adequate to connect to a source of power. However, if you must extend the
power leads, be sure to use at least a good quality (type TEW) wire of at least the same gauge
as supplied with the unit. The wire colours are:
• Red: Positive connection
• Black: Negative connection
All connections should be made inside an appropriate junction box. Refer to the specifications
table for the correct sizing of the circuit breaker in the distribution panel. A ground stud is
provided to bond the chassis to local ground to reduce or eliminate EMI.
OUTPUT CONNECTIONS
This unit is equipped with two Positive output terminals and two Negative output terminals as
DC output connections. Connect only one wire to each terminal. Ensure that the total average
load connected does not exceed the continuous current rating of the unit.
To ensure spark free connections the power switch must be in the OFF position prior to making
the connections to the load(s).
IMPORTANT: For 12VDC Model Only!
For 12 VDC model, the output terminals must be connected in parallel as shown below if
the load current is greater than 50A
